HoG oILER I Filed April 1o, 1961"y United Sites arent O 3,101,072 HOG OILER Louis A. Smith, RR. 1, Denver, Ind. Filed Apr. 10, 1961, Ser. No. 101,952 4 Claims. (Cl. 119-157) This invention relates to an apparatus for the rubbing, treating and oiling of animals and particularly hogs, the rubbing being accomplished by the hogs themselves.

A It is known in the `art to provide a station or apparatus set up in ya suitable llocation so that hogs may rub thereagainst to scratch themselves `and to coat or iinpregnate their skin or hides with a liquid oil, insecticide Ior the like. It has been found that presently available `apparatus of this nature have a number of imperfections which prevent them from performing their intended function in the most facile @and Aefficient manner. For this reason, it is .a general and primary object of the present invention to provide an improved apparatus ttor the rubbing, treating and oiling of ianimals such as hogs. p

A further object of the present invention is to provide an apparatus for rubbing and oiling of animals which apparatus is relatively simple and inexpensive to manufacture, yet is capable of performing its desired function in an efficient manner.

Still another object of the present invention is to provide a device of the present character which maintains constant the rate of delivery of the oil to the anirnafls coat no matter how recently oil has been 'added to the apparatus.

Still :another object of the present invention is to provide an :apparatus Iof the present nature' incorporating an improved rigid means against which an animal can scratch himself, said rigid means incorporating improved structure for spreading oil over the surface thereof. v

Related objects and advantages will become apparent as the description proceeds.

, One embodiment of the present invention includes a horizontally extending base, `a support extending upwardly from said base, said support acting as an 4oil reservoir, means [for maintaining the oil within said reservoir at a constant level, an elongated ilexible `element secured at one end to said base, la weightsecured to the other end of said flexible element and hanging thereon in said reservoir, said elongated element bei-ng sufficiently long that its other end is submerged within the toil in said reservoir whereby `an animal rubbing or forcing [against said iiexible element tendsA to draw the other end of the flexible element upwardly and to cause oil to run down the flexible element from the other end thereof toward the ibase.

The full nature of the invention will be understood from the accompanying drawings and the following desoription and claims.

FIG. l is a perspective view of a hog oiler constructed according to the present invention.

FIG. 2 is :a vertical section through the hog :oiler of FIG. 1.

FIG. 3 is a fragmentary perspective view of a further embodiment of the invention.

lFor the purposes of promoting an understanding of the principles of the invention, refer-ence will now be made to the embodiment illustrated in the drawing and specific language will be used to describe the same. It will nevertheless be `understood that no limitation of the scope of the invention is thereby intended, such alterations :and further modications in the illustrated device, and such further applications of the principles of the invention as illustrated therein being contemplated as would normally occur to one skilled in the `art to which the invention relates.

ICC

Referring now more particularly to the drawings, there is illustrated a hog oiler including a base 10i made up of lumber such as, for example, 2 x 4s as bracing elements 11 land l x 6s for the ilooring 12. Secured centrally to this -b-ase 10 is la plate 15 having an upright pipe 16 (such as, for example, -a three inch diameter pipe) suitably secured thereto as by welding 19 or the like. Secured to the upper end of the pipe 16 is a rack or retainer 17 including an annular rin-g .18 and radially and vertically extending elements 20 securing the ring to the support. The rack 17 receives va generally :cyclindrically shaped tank 21 having a spout 22 secured thereto and forming the only exit for the tank. lIt should -be mentioned that the spout Z2 may be threadedly received within the tank so 'as to be removable therefrom, if desired, to facilitate placing oil within the tank.

The pipe 16 is sealed to the plate 15 and forms therewith a container 1.or reservoir for oil which `is maintained at a :constant level by `reason of the f-act that there is no other exit lto the tank 21 than the spout 22. Thus, whenever the oil level within the support moves downwardly away from the lower end of the spout 22, more oil flows into the support and brings, the level back up to the spout.

Formed at the upper end portion of the support 16 are a pair lof slots 2.5 terminated at their lower `ends by means of thickened portions 26 which act as bearings across which are moved chains 2.7. The chains 27 are illustrated as straight link chains for the purpose of ease of illustration. Such a straight link :chain is very denitely workable in the present invention; however, a twist link machine chain as is fragmentarily shown at 28 in IFIG. 3 is preferred for the reason that the oil dlowsmore easily therealong. The chains are secu-red at their lowerrnostA and outermost links 30 to the base 19 by suitable bolts 29 and extend upwardly and inwardly to the support through the slots 25 and hang downp wardly in the support. Secured to each of the endward links 31 IWithin the support is a weight 32 which norinally retains the endward portion of the 'chain within the support and normally submerged within the foil 35 in the support. When an animal moves against either ofthe chains 27, the submerged portion of the chain is *drawnupwardly and out of the support to a position above the remainder of the ichain thus causing the oil carried with and temporarily adhering to this formerly submerged portion to run downwardly onto the remainder of the chain.

Thus, as the hog or yother animal rubs against the chains, its skin `or hide is coated or impregnated with oil. When the animal moves away from the chains 27, the weights 32 again return them to the illustrated p0- sition. It should be noted that the amount Aof oil delivered to the chains Z7 is controlled or adjusted by securing dilerent links (near the link 30) to the base by the bolts mentioned above. Thus, less of the chain is dipped in the oil. It should also be noted that the weights 32 are somewhat larger than slots 25 and therefore, cannot be pulled therethrough by the hog.

Secured tothe outside of support 16 is a helical element 40 which is' ixed to the support atv the upper end of the helical element and also at the lower end thereof. It should ibe emphasized that the various convoiutions of this helical element `are spaced yfrom one another and thus, any toil flowing downwardly on the outside lof the support will be permitted to iiow a substantial ydistance vertically but will also be provided with a rotating motion causing the lcomplete outer surface of the support to 'be covered with oil. Obviously, this oil will be supplied to the louter surface of the support by reason of spillage occurring each time one or both of the chains are withdrawn from the support. 'It should Y be noted thatV the support 16 is rigid in nature and will not given or yield when the hog moves thereagainst.

Fnoin the above description, it will be evident that the present invention provides an improved device for rubbing, treating and oiling `of animals and particularly hogs.` It vwill be obvious from the above description that the present device is sirnple and inexpensive to manufacture, yet is durable and capable of doing the job required in an efficient, manner.

While the invention has been illustrated and described in detail in the drawings and foregoing description, the same is to be `considered as illustrative and not restrictive in character, it being understood that only the preferred embodiment has beensho'wn and described and that all changes and modiications that borne withinv the spirit of the invention and the scope of the claims are also desired to 'be protected.
